..Few data exist regarding the outcomes in patients undergoing surgery for pelvic tumors of neurogenic origin. Our aim was to characterize the clinical and pathologic features of pelvic neurogenic tumors and assess surgical outcomes...

..Given the low failure rates of porous tantalum acetabular implants in other conditions with large bone loss or irradiated bone, we developed a technique to use these implants in these neoplastic cases where others might fail...

..Peroneal nerve function, knee stability, and recurrence are substantial concerns with these resections. The incidence and fate of these complications is not well-known owing to the small numbers of patients in previous reports...

..The objectives of this study were to describe the authors' experience with the timeline for prosthetic fitting after rotationplasty of the knee and to determine factors that may be associated with earlier prosthetic fitting...

Vascularized free fibula transfer for oncologic reconstruction of the humerus

..To determine the age and gender distribution and imaging features of low-grade central osteosarcoma (LGCOS) of the long bones and pelvis and to discuss our findings in the context of lesions for which LGCOS has been mistaken...

Follow-up study of long-term survivors of osteosarcoma in the prechemotherapy era

..Sacrococcygeal chordoma presents a difficult diagnostic and therapeutic problem, with a high rate of local recurrence. The purpose of this report is to define the importance of adequate surgical treatment for optimum outcome and survival...

..M-OGS combines multiple skeletal locations of high-grade conventional osteosarcomas and has a poor prognosis. Aggressive surgery may result in improved long-term survival, particularly in patients with metachronous disease...

..The difference in survival was not apparent until after 5 years and was more pronounced after 10 years. Recurrence may be regarded as a declaration of an aggressive phenotype and should be treated as such...

Periosteal osteosarcoma: long-term outcome and risk of late recurrence

..Multimodality treatment has dramatically improved the outcome of patients with Ewing sarcoma. However, there appears to be little information concerning treatment-related complications in patients who are long-term survivors...

..The goal of this prospective study was to determine the outcome of double level osteotomy of the knee performed after analysis with computer-aided preoperative planning software in patients with varus malalignment...

..Neurological status deteriorated over time with 57% of patients progressing to functional stages IV or V, although consistent improvement was noted for pain relief. Function was directly related to the stage of the neurological disease...

..We evaluated the effect of the use of recombinant human osteogenic protein-1 (rhOP-1) combined with allogenic cortical bone strips as a substitute for an autogenous bone graft for extracortical bone-bridging...

Mechanical effects of partial sacrectomy: when is reconstruction necessary?

..The orthopaedic oncologist is a vital member of a team composed of musculoskeletal radiologists and pathologists, radiation oncologists, medical and pediatric oncologists, and microvascular surgeons...

Does the second-generation intercalary humeral spacer improve on the first?

..We noted improvement in Musculoskeletal Tumor Society scores from preoperatively to postoperatively in both groups. Use of these implants should be reserved for patients with limited life expectancy...

Clinicopathologic features, diagnosis, and treatment of fibrosarcoma of bone
